We currently have a potential Cat 4 hurricane approaching and that for the first time made me worry about prolonged power outages and consequences for my tank. Since I moved into my current place, we only had one major power outage (12+ hrs), once, and that was before I had my tank up. Since then, no power outages (*knock on wood*), but shorter outages (a few hours) are common in the general area. Hence, we did not yet feel the need to buy a generator (hurricanes are very very rare - so are blizzards :p )
How long can a 40 gal FOWLR tank go without power? It's not cold, so I'm not too worried about heating. But what about the filter? I have a normal stack on filter, no elaborate setup. But, I thought, beside filtering of course, it's needed for keeping the water oxygenated?
You can buy an icecap battery backup to power a small powerhead for a while. I don’t remember the exact numbers (as to how long it will run the powerhead) but it might work perfectly for your 40.
